“…The fundamental reason for this social cost expenditure on obstetric diseases is that it is difficult to predict and diagnose maternal and fetal diseases early, and therefore, even if the disease is found, the effectiveness of treatment is low. The area under the receiver operating characteristic curve (AUC) for diagnosis of conditions, such as preterm birth, preeclampsia, fetal growth restriction, and stillbirth, which are relatively common but have a significant impact on maternal and fetal health, has been reported to be 0.51-0.85, 0.61-0.99, 0.54-0.98, and 0.58-0.76, respectively [2][3][4][5][6][7][8][9][10]. Evidence-based traditional research methodologies have been the main tools used to solve problems related to obstetric healthcare.…”
